Explainable Machine Learning Combined with Feature Selection and Bayesian Optimization for Predicting Rare Earth Elements and Yttrium in Coal: A Case Study of China’s Five Major Coal-Bearing Regions

Abstract Determining the concentrations of rare earth elements and yttrium (REY) in coal is essential for evaluating coal-hosted critical metal resources and understanding their geochemical controls. However, conventional laboratory analyses are costly, time-consuming, and spatia...

PDMS-based flexible packaging method via a 12-inch RDL-first process for conformal electronic applications

Purpose This study aims to realize large-scale and high-density manufacturing of conformal electronic devices by proposing a polydimethylsiloxane (PDMS)-based flexible packaging method via a 12-inch wafer-level redistribution-layer-first (RDL-first) process. Design/methodology/ap...
